I just do not know how children may like it! It is terrible taste of oil, reminds me castor and tamanu oil together. I thought it would have some tasty smell. I tried it on myself first ((((((((( yes, it gave the effect of frozen tongue, for a while, may be 20 minutes, not more. And I couldn't get rid of the taste for hours.
Then I tried to give just a drop of it to my baby. She started to cry.
Кошмарище! Меня начало тошнить от этого вкуса и малую тоже. Она расплакалась и слюни полились рекой. Подморозило язык может на минут 20, не больше (на себе испробовала). Одним словом - не рекомендую...

Already bought a second bottle. This stuff really works for my teething baby. I see her calm down within seconds after I apply the oil on her gums. And since it's all natural oils and herbs I don't need to worry about the safety of this product. In one word, it is AMAZING.
